    1. INTRODUCTIONThis manual describes the installation and operation of the Wirsbo Genius System. Wirsbo Genius is a complete system for room-by-room control of underfloor heating systems in homes, offices, industrial sites, etc. The Wirsbo Genius system relies on radio signals to transmit temperature information from each zone to control the temperature in that zone. There are many programming features designed to optimise control of the underfloor heating system.

    The system is fast and easy to install and is ideal for both new and renovation projects. Wirsbo Genius is CE marked and has been approved for use in EU countries and all of the EFTA countries.

    Wirsbo Genius consists of three key components: The Control Unit, the Programming Unit and the Thermostat. The Control Unit and Programming Unit are supplied together in one box and are often referred to as the Base Unit.

    Control unit: This is connected to 230 V AC power supply. It controls up to 12 24 V actuators (which are wired into the unit) and up to 12 Genius room thermostats. It is normally located near to the manifold.

    Programmer unit: This keypad and display is connected to the control unit with a cable. It can be located any convenient position. The user can control the system and programme the settings of each individual room thermostat, set-back temperatures, etc. The Programming Unit has a built-in radio antenna to receive the signals from each individual room thermostat. If the signal is not satisfactory, an external antenna can be plugged into the programming unit to boost the reception.

    Thermostat (Thermotransmitter): As in other room control systems, one thermostat can control one or several loops, as required. The thermostat can be positioned in the room in the normal way by mounting it on the wall. The grey bulb on the thermostat senses both convective and radiant heat to achieve optimum accuracy. The room temperature is set by turning the bulb. The min/max limits of the thermostat are programmed at the programming unit. Two versions of the thermostat are available: switch and display. The thermostats are battery powered.

    A complete system is shown below at Fig 1.

    2. ROOM THERMOSTAT

    2. 1 External designThe temperature sensor is located under the grey bulb, which is manufactured from thin aluminium. The domed shape of the bulb quickly senses both convective and radiant heat.

    2.2 Setting the temperatureThe temperature of the room can be set by turning the bulb. The programmed values are pre-set to minimum +10C and maximum +28C. Min/Max settings for each thermostat can be changed at the programmer (see 6.8).

    2.3 Types of thermostatSwitch thermostat: Turn the bulb to set the required tempe-rature. The switch has three settings day, night and timer. In the day mode, the thermostat operates according to the set-temperature. In the night mode, the set temperature of the thermostat is set-back by 4C. In the timer mode, the set-back temperature setting of the thermostat is as programmed.

    Display thermostat: Press the grey bulb to view SET temperature. Turn bulb to required temperature and press again to accept the new temperature. The thermostat will show actual room temperature again. Press and hold the bulb for approximately 20 seconds to change the setting from C to F and back again.

    2.4 BatteryEach thermostat is supplied with a 3.6 V 1900 mA Lithium battery. Batteries will last approximately 5 years in the dis-play thermostat and approximately 10 years in the switch thermostat. It is advisable to change all batteries after 5 or 10 years to avoid unnecessary problems.

    The battery can be changed by house-owner. Make certain that the new battery is correctly connected. If not the thermostat may be seriously damaged. Never attempt to recharge the battery.

    After replacing any battery, the thermostat must be run in the Test Mode (see 2.8 and 6.6) to ensure that it functions correctly.

    2.5 OperationEach room thermostat is installed and programmed with its own identification number. This ID-number is transmitted every time temperature information is sent to the base unit. The ID number enables the base unit to distinguish between the various room thermostats and prevents confusion with other neighbouring systems.

    Each room thermostat sends control signals with tem-perature information between 2-30 minutes. The room thermostat transmits data as soon as the room temperature changes by 0.25C or as soon as the set temperature is chan-ged. When the room temperature setting is maintained, the transmitting interval is 30 minutes.

    2.6 Installation (see 6.4)The black cable supplied with the base unit is used to programme each thermostat. Connect the cable to the rear of the thermostat, behind the battery cover (Fig 4) to the Control unit.

    The first available channel will start to flash on the Programmer screen. Press OK to accept or scroll to the preferred channel using the arrow keys.
